Guinness World Records has recognized farmer Aharon Shemoel for growing the world's heaviest lemon on his farm in Kefar Zeitim, Israel. The citrus fruit grew next to another huge lemon; it weighed 5.265 kg. The fruit's circumference was 74 cm and it was 35 cm high; measured on 8 January 2003.
Aharon's lemon broke the long-standing record that was held since 1983 by Donald and Charlotte Knutzen of Whittier, California, who grew a lemon weighing 3.88 kg.
